My Environment： OS:Windows 2003 sp2,Tivoli Productivity Center(TPC) 3.3.2.118,SMIAgent 120.10. My Operation: There is a firewall between TPC and SMIAgent.I have opened the ports 897,898,111 from TPC to IBM 2109-M48 switch .Then I can ping each other successfully.But I can't add the user 'admin' which can be accessed remotely into the SMIAgent.I don't know the reason. My Question: I want to know which reason(s) can make the SMIAgent not been added the M48 's user 'admin' successfully? I hope your help,Thanks!
